Analyzing Multiphase Flow in Horizontal and Deviated Wells
Production logging determines where gas, oil and water enter a wellbore and measures the flow rate and relative percentage volume, or holdup, of each phase. In horizontal and high-angle wells, the phases often stratify, so conventional logging techniques using a fullbore spinner do not capture the details of multiphase flow. A new tool has been designed for high-angle wells that can analyze multiphase flow across a complete wellbore. This article describes the Flow Scanner tool and its successful application in the Gulf of Suez and the North Sea.
